The 23rd Thailand-Japan Conference on Discrete and Computational Geometry, Graphs, and Games (TJCDCG3 2020)

December 5 - 7, 2020
at Department of Mathematics
Faculty of Science, Chiang Mai University, Thailand

Due to the COVID-19 situation, we will make a decision whether to postpone or to continue TJCDCG3 2020 by the end of July 2020.

Conference Overview

       The series of the Japan Conference on Discrete and Computational Geometry, Graphs, and Games (JCDCG3) has been held annually since 1997. In 2012, the series of the conference was held at Srinakarinwirot University in Bangkok as “Thailand-Japan Joint Conference on Computational Geometry and Graphs (TJJCCGG 2012)”. This year, the conference comes back to Thailand again at Chiang Mai University. We have hosted many international academic events in mathematics, and it is our great pleasure to welcome everyone in this place, where nature nurtures beautiful intelligence.

       Scope of Conference includes, but not limited to: Discrete Geometry, Computational Geometry, Graph Theory, Graph Algorithms, Complexity, and Winning Strategies of Games and Puzzles.
